Don't start me about NON Chihuahua's in my house though... the chis become a band of mean little stalkers.. ha ha

THAT is funny! I picture your two intimidating some big Bull Mastiff into a corner. haha!

I have 3. Hope and Ruby we got 2 months apart. We added Eden 8 months later. All female and they get along great. Two sets of trainers/behaviorists who have worked with us in our home have remarked that they have a great dynamic.

Hope and Ruby are especially close since they were puppies when we got them and just 8 weeks apart. Ruby sometimes bosses Eden and Hope, who is the mediator will always be sweet and let Eden lay down by her.

My three are SOOOOO different. I suppose it would make a difference if they were all similar in temperament.

My two are very similar (they are related after all!) and they are the calmest dogs you could meet, my male is the social outgoing one ( I take him everywhere) and the female is my husbands dog and she's very quiet and shy and likes to observe new people in our home.

When it comes to dogs, the female avoids and dislikes ANY dog that is not a Chihuahua, we can be walking down the street and she will just AVOID.. ha ha Bijou does not care so much, he'll stop and sniff and check a new dog out.
Its weird my dogs can spot another Chi before I can.

In our home?? omg forget about it! We had a larger breed puppy with us for a few weeks and they were abysmal! little tyrants! one would guard her food bowl and not let her near it.. the other one would hide under the china cabinet and dart out attacking her legs as she trotted by.. I should not laugh but it was really funny to watch them be such little ***ts! Bijou even tried to bite her face! I have never seen anything like it, but when the other Chihuahua's come over? it's like a Mexican fiesta! they all hang around groom each other.. and prance around in a pack. My dogs also seem to like cats, not sure if that's chihuahua specific though.

My 3 get on great and there is def no bullying at all! U will just notice their different personalities, they might hav a wee growl here and there over food and toys but that's normal and they are all friends ultimately and fret if they aren't all together.

Yeah, I,m expecting the little growls and stuff, but I,m not worried about anything really, they will all get along, i would not get the next two together anyway i think it would be better to introduce one dog at a time anyway. I have alway,s had dogs, they have been a big part of my life and now the kids have left i really love to spend time with my Charchi and really ready for more. I dont have any hobbies anymore and I,m on a disabled pension, so i have all the time in the world so I,m going to spend it with more chi,s, cant wait.

I had 2 girls and 1 boy for quite a while and they all had different relationships with each other. Adam and Heidi didnt get on for a while but are now ok with each other. Heidi and Hannah are BFFs and like to sleep together, and Heidi hates walking without her big sister. Hannah and Adam get on really well and love to play rough and tumble games (to which Heidi is abit to timid to join in).
Now I have Alfie as well and it has turned out great, Heidi finally has a playmate for proper fighty/bitey games and the dogs tend to pair off to play!
I def agree that its more about matching personalities and temperaments then how many you have.

I have three chi's, all females. All spayed. One longhair 8+years old, one shorthair, 4+ years old and one longhair 9 months old. The puppy tries to play with the others, and many times she gets them going. Most of the time they look at her with the air that says 'again, you want to play, get lost". Maybe if I got them closer together in age it would make it easier for them to play together.?

I have 2 chi's and they love each other so much...my Shih Tzu is unsure about this whole operation and her world has been turned upside down in the last month. She doesn't care for the Chi's much on most days...
